2004 ford explorer exterior lights?

[Casey C]

I have a 2004 ford explorer and was wondering what I have to do to make the exterior lights illuminate when I press the "Unlock" button on my keyless remote. My parents have a 06 explorer and there exterior lights turn on for about 30 seconds when they unlock there's, how do I do this to mine?

Thanks!
